matthew stapleton says that's when he realized the actions of these suspected predators have had far-reaching consequences. >> there were spouses and children that were devastated when they learned of this development and their lives were upsidedown. >> so it's not just this guy out there. there's collateral damage in these cases a lot of people affected in a sad way. >> you made it. >> yeah, of course. >> and there are many more men about to turn their lives and lives of their families upsidedown. so far, we have introduced you 11 men. that's not even half the tote am number of suspects who show up at our hidden camera house. >> i wanted to get into something sexier for you. >> next time, we'll introduce you to the rest of them. as you'll hear, many of them like this doctor claim they're innocent. >> oh, man. >> for information on how to protect children from internet predators, log on to our website. you'll find a complete online safety guide for parents and teenagers. the address is dateline.msnbc.com.

it that's all for now. i'm stone phillips. for ann curry and all of us at msnbc, thank you for watching. ?h

hi, how you doing? >> you act like this is some big joke here. >> these were people that were in the shadows, and now they have been exposed. >> my seasoned detectives and myself were shocked at what we saw happening. >> i believe that we would have had some young child sexually abused. >> "dateline's" groundbreaking series is back. >> i'm not really a predator, sir. >> you're not a real predator? >> no, sir. >> just a pretend predator? >> men targeting children online. >> a field trip in florida. >> so you drove 60 miles to see a 14-year-old girl? >> a repeat rendezvous in california. >> you know, you look familiar to me. >> oops. >> and arrest after arrest after arrest.

>> oh my god! >> put your hands up. >> the latest on the series that's changed laws and lives. >> if "dateline" had not been there, there could have been 51 victims. >> through a click of a mouse your child can go visit and talk to people that they have never talked to. >> it's time for all of to us wake up. >> chris hansen goes coast to coast "to catch a predator." >> thanks for joining us. i'm stone phillips. >> and i'm ann curry. this time we're in long beach, california, where the long arm of the law has reached out and grabbed three dozen men in just three days. >> put your hands above your head. >> this time someone's gone online to post a warning our hidden cameras are in the neighborhood. but think that stopped these men? a reminder of some of what you are about to hear and see is explicit. here's chris hansen. >> what do we have coming up right now? that's our avalanche.

that's our 12:30. like 29 years old. >> we've always been aware that the men coming into our undercover houses could be dangerous. >> now, stay there. we don't want to send you out yet. >> but as we set up our "to catch a predator" operation in long beach, california, the very first man who arrives has us especially worried. >> whoa, hold on, here he comes. he's coming. >> whoa, hold on, here he comes. head to position 3. >> 29-year-old michael warrecker, an unemployed computer technician, uses the frightening screen name, can i rape you anally? he thinks he is coming to meet a girl who says she is 13. >> open up the door. >> what warrecker apparently doesn't know is he's really been chatting with an adult decoy from perverted justice. that's an online watchdog group dateline uses as a consultant to do what it normally does, go into chat rooms, mostly on yahoo and aol, set up computer profiles and, in this case, pretend to be children under the age of 14 who are interested in sex. >> okay. that's cool. >> in his online chat, warrecker tells the decoy maybe we should hook up and says he would like to have anal sex with her. the decoy says, "ouch, i think

that would hurt a lot." warrecker responds, "yeah, but it's a good pain, you know." >> now warrecker is at the door. >> hi, how are you doing? >> being met by a youngish-looking 18-year-old decoy playing the girl who's supposed to be home alone. >> can you sit down? >> and it's time for me to have a chat with him. >> we have a lot to talk about. >> though my arrival doesn't seem to faze him one bit. >> this is punch, right? >> yeah. what are you doing here? >> hanging out. >> hanging out? >> yeah. >> and i knew that this was a setup because this was too convenient for this. >> what was too convenient? >> the chat room and just talking about everything that she did. >> how old was this so-called person you talked to? >> she said she was 13. >> she said she was 13. how old are you? >> i'm 29. >> and you thought it was okay to come over here and meet a

13-year-old girl at the age of 29? >> and hang out, yeah. >> that's all you were going to do was hang out? >> that's what i told her. yes. >> but remember, we have his chat log, where he writes to someone who says she's a 13-year-old female, "i like rape." she responds, "creepy." warrecker explains he doesn't really want to rape her. just rough sex. "i would want you to resist and pretend you didn't want it and stuff." >> what kind of a guy has a screen name, can i rape you anally? >> it gets responses. >> do you think rape is fine? >> no. >> then why would you do? >> it's just something i like to put myself into that role and talk about. you know? >> warrecker also asks online if he could tie the girl down while they're having sex. and it gets scarier when he goes on to add, "i might want to cut you a little, suck on your blood, laugh out loud." >> a trait that i look for is, you know, they enjoy a little bit of pain here and there, you know. >> you've had girlfriends who enjoy a little bit of pain?

>> yeah. >> well, how many times have you had a conversation like this and actually met somebody to fulfill this rape fantasy? >> never. >> never? >> no. i thought it would be cool to hang out -- >> you thought it would be cool to come over here after having a chat somewhat like this -- "so if i wanted to just bend you over and just shove it in your [ bleep ] and it hurt pretty bad, you wouldn't do anything, would you? "yeah, i would scream and try to hit you." you act like this is some big joke here. >> sir. >> those are your words, not mine. i'm not making this up, right? this is stuff you said. >> that's correct. >> to somebody who said she was a 13-year-old girl. >> yes. >> what do you for a living? >> actually, right now i'm unemployed. >> unemployed? >> i got a small inheritance a year ago and sort of took a break. but i'm almost out of money now. >> time to go back to work. >> yeah, it's back to work. >> warrecker tells me he's brought along a scary movie to watch with the girl, a video camera, and lubricant. >> a video cam. >> is this any way for a 29-year-old man to behave? >> no. >> have you ever watched "dateline" nbc? >> sometimes. >> i'm chris hansen with "dateline nbc." we're doing a story on adults

who try to pick up young boys and girls online for sex. if there's anything else you want to tell us about why you're here and what you've been doing, we'd like to hear it. if not, you're clearly free to walk out the door you came in. >> and just outside, the long beach police are getting into position. >> hands up in the air. >> he is charged with an attempted lewd act upon a child. under california law, attempting to have sex with someone under the age of 14 is a felony, punishable by up to four years in prison. warrecker pleaded no contest. he's the first in a long line of men who will be arrested by the long beach police department over the next three days. >> who's all here? >> just me. >> later in our program you'll see a first for us. someone who showed up at one of our earlier investigations, unbelievably, shows up for another visit. >> you know, you look familiar to me.

hi, how are you? >> this is the third time we've set up an undercover house in california. for the long beach police, it's a big operation. sergeant lee debraybander is in charge. >> just playing this alone was a huge event. we had surveillance all over the place in undercover vehicles. we have the arrest team in place. we had in excess of 25 officers on this at any given time. >> and it's challenging for us as well as more potential predators become aware of our investigations. look at this posting on the craigslist website, presumably warning internet predators that "dateline" is in long beach. and on our first day some show up but never come in the door. >> will. all right.

>> like this man, who doesn't like what he sees and pulls a u-turn even as the decoy waves him in. >> i think he's a goner. >> do you want to sit down and get a drink? i'm going to get something really quickly. i'll be right back. >> yeah, sure. >> did you bring everything with you? >> yeah. >> awesome. i'll be right back. >> this man might have gotten a look at our camera crew behind that curtain. >> he's running. he's leaving. >> can you do me a favor, though, really, really quick? can you pour me a drink? and i'll be right back. like two seconds. i promise. wait, wait. stop, don't you want to hang out in the hot tub? >> no. >> or it could be that they've seen our investigations and become suspicious. >> all right. police. >> oh my god! >> put your hands up. >> no! >> put your hands up and drop to your knees. >> coming up the driveway. >> but in the case of this man we think we know exactly why he doesn't come in the house. 41-year-old matthew bland, screen name blandmatthew, chatted online with someone who

says he's 13 years old. bland asks the boy, really an adult decoy, if he's ever had sex before and explains the other sexual acts he says he will perform on the teen. he also sends along a picture of his genitals. [ doorbell ] but when bland approaches our house hoping to meet a boy, we mistakenly send our female decoy to meet him. >> hi, how are you? >> hi. is timothy here? >> timothy? >> yeah. >> i don't think so. >> maybe i got the wrong address. this is 5278, correct? >> yes. >> huh. my apologies, i must have gotten the wrong address. thank you. >> he has the right address but remember, according to his chat he was expecting a young boy. bland tries to leave, but the long beach police have another plan. >> put your hands up. long beach police, put your hands up. stop right there. stop. put your hands all the way up. straight up. turn around. >> even though bland didn't come inside, his explicit online chat

and his showing up at the house are enough for him to be charged with one count of an attempted lewd act upon a child. he later pleaded no contest. >> i think this is our musician, sugar davis. >> at our undercover house other men keep arriving. >> his name is mattie. >> this is matthew nash, a 36-year-old musician, screen name sugar davis. he drove about an hour to get here. >> how are you doing? >> not bad. >> good. >> nash was told he was chatting online with a 13-year-old girl. he talks about getting naked in a hot tub with her, smoking marijuana, and putting oil all over each other's bodies. that's apparently why he has decided to come inside. >> come on in. are you excited? yay. i'm excited. >> yay. yeah, i'm -- it was definitely a long drive, you know, coming down here. >> did you bring any weed?

>> mm-mm. >> no? >> no. >> why? >> you didn't bring your drums? or -- >> no. >> why don't you have a seat over there. >> no. >> i need to talk to you for a minute, sir. >> uh-uh. >> outside the long beach police are waiting. at the processing center investigators find condoms, baby oil and a vibrator in that bag nash was carrying. and he tells the police he's married. >> how long have you been married? >> 13 years. >> ever been caught doing this before? >> no. >> got any kids? >> no. >> is she aware of this type of behavior? >> yes. >> he also tells police he and his wife have been to counseling because he's met others online for sex. sergeant debraybander says the consequences of arrests like this one impact suspects'

families. >> those are the people i really feel sorry for. they had no idea. it was totally out of their control. and now because of the actions of this one person, you know, they're affecting all these other people who they're supposed to love and care for. >> nash pleaded no contest to one count of an attempted lewd act on a child. >> okay. go out to position 2 and wave him in. >> in the meantime, it's getting busy at the house. and the men who show up are a little more willing to stay a while. like 24-year-old selvin galeano driving up in his customized nissan altima. >> hey, come on in. sorry, i still have to do my hair. just have a seat. can you get me a drink? >> galeano, who works installing custom stereo systems, chatted online using the screen name nismo 05007 with a girl who says she's 13. he asked if she is a virgin and if she's tried oral sex. and he says he'll lick her all over her body. >> i'll be right back, all right? >> all right. >> that's quite a car you've got out there. >> thanks. >> why don't you have a seat. what do you got going on today? >> nothing. just hanging out. >> hanging out?

and you were going to come here to hang out today? >> well, yeah. i got to go to my friend's house after. i've got to pick up some of my stuff. so she just told me she lived down here too. >> who is she? >> i met her a couple days ago. >> and where did you meet her? >> online. >> online. and how old is she? >> she told me she was 16, 17. >> she told you that she was 16 or 17? >> mm-hmm. >> now, you know that's not true. >> how old is she? >> she told you. >> first she told me 13, and i was like, are you sure you want to talk? she's like, yeah, sure. >> so that 16, 17 thing was a lie you just told me. >> well at first i thought no i think you're 16 or 17. you look 16 or 17. she sent me a picture. >> you know, i read the chat log. >> oh, you did? >> yeah. >> okay. >> you might as well start telling the truth now. >> okay. she told me she's -- >> 13. >> then we hear the same story we've heard many times before. >> i never chatted with anybody

like that. >> so this is the first time you have ever chatted with somebody? >> first time. >> did you bring condoms? >> i don't carry them -- well, they're in my car. >> you have condoms in your car? >> yeah. >> what does that say about your intent here? >> i wasn't -- if i was going to bring condoms, i should have just brought them. >> or you could see how things go and go out to the car and get them in case somebody caught you here and you had them in your pocket. >> right. >> okay. what do you think should happen to you? >> i really regret this. >> you regret it? >> right. >> do you ever watch television? >> most of the time i'm working. >> well, there's something you've got to know, and that is i'm chris hansen with "dateline nbc," and we're doing a story on adults who try to meet kids on the internet for sex. >> he leaves us with an apology. >> it's not right to just go in and talk to any young girl or person. >> just like the other men, galeano will be charged with one count of an attempted lewd act upon a child. he later pleaded no contest. >> i would ask you to go out the back way. i'll show you how to go out that way. >> "dateline's" security team asks galeano to go out the back door. that's because right out front is the next man you're going to meet.

>> sir, please. >> i want to show you something. >> sir, please. >> coming up, this man has a good reason to cover his face. >> and do you know what the show is called? >> yes. >> what is it called? >> "dateline." >> "dateline." >> and there will be other men. some who apparently want to make a day of it. this 44-year-old father of three thinks he's staying for lunch. >> okay. >> did you bring sandwiches? >> sure. >> awesome. i'll be right back. >> okay. please. what's this? uhh, it's my geico insurance id card, sir. it's digital, uh, pretty cool right? maybe. you know why i pulled you over today? because i'm a pig driving a convertible? tail light's out.. fix it. digital insurance id cards. just a click away with the geico mobile app.

he's sitting in the car in the front. >> it's busy at our undercover house in long beach, california. >> okay. he's getting out of the car. >> just hang tight and we'll go to the front door. >> remember, we asked our previous suspect to out the back way so he wouldn't scare off our next visitor. >> hi, how are you doing? come on in. >> he's paul clemente, a 22-year-old college student from san diego.

clemente spoke online with someone he thought was a 13-year-old girl. at first clemente says she's too young. but soon asks her if she's had sex and what positions she's used. finally, he gets down to business. >> so when's the time i can come to your house? of course when your mom is not around. i'm asking when, so we can ge out. >> clemente asks if she's had sex in a hot tub. when the decoy answers yes, he writes back -- >> you're making me horny. >> for good measure he sends along this picture of his penis. then he tells her something that really surprises us. >> you're going to be my first. >> that's right. he may think she's 13, but he's the one who says he's a virgin. now the 22-year-old virgin is in the house. >> all right. can you pour me a drink really fast? >> sure, no problem. >> thanks. awesome. yeah. i'm just going to get my hair ready. i'll be right back. >> take your time.

>> sir, please. >> did you send that to her? >> yes, sir. >> to somebody who said she was a 13-year-old girl? >> oh, my god. sir, please. >> why did you think that was an okay thing to do? >> sir, she said it's okay. >> she said it's okay. so because a 13-year-old girl says it's okay, you do it? >> sir, please, i'm not -- i'm not a really bad person, sir. please. >> as for that claim that he didn't say anything bad online, what about telling her he will perform oral sex on her or asking if she has ever had anal sex? >> have you ever had conversations like this with teenage girls on the internet before? >> no, this is my first time. >> your first time. you know, i hear that a lot. can you imagine why i'm a little skeptical on that? >> sir, please. >> virtually everybody that walks in this house says the same thing. >> i'm sorry. >> and i'm getting that not everybody is telling the truth. >> sir, i'm sorry, sir. >> and as we suspected when clemente first covered his face, he knows that there are cameras in the house. >> do you ever watch television? >> yes. i know, sir. >> you know what? >> this show, sir. >> this show? >> yes, sir. >> have you seen the show on television? >> yes, a couple of times. >> a couple of times. and you know what the show is called?

hello. at least two people are reported dead after a private jet went

down in a south bend, indiana neighborhood. two of the four people on board the plane were killed. the neighborhood has been evacuated because of concerns over jet fuel. vice president joe biden in is rome to celebrate pope francis. pope francis spoke to more than 100,000 people this morning in st. peter's square. more news later. now back "to catch a predator." do you want me to call for him? where is he? come on in. how was the drive? >> good. >> we hired this 18-year-old actress as a decoy. here pretending to be a 12-year-old alone in our undercover house. the man who's coming to visit her is 29-year-old james cisneros. his screen name is too graphic to say on television. almost right off the bat cisneros asks an apparent 12-year-old online --

>> do you like sex? >> who doesn't? >> me, too. you want to hang out tonight? if you're not busy. >> she tells cisneros that he can't come over now because her mother is home. >> oh, can you sneak off late tonight and we can get a hotel and i will drop you off and you sneak back in? >> what for? >> sex. >> you heard that right. he wants to take someone he thinks is a 12-year-old to a hotel for sex. but the decoy won't budge. so cisneros gives in and shows up at the house. >> so i made a drink. i don't know if you want to try it or not. it's kool-aid. >> is this regular kool-aid? >> yes. >> and he comes prepared. >> what are you doing? did you bring condoms? >> yeah. you want them -- anywhere? >> it doesn't matter. >> take a taste of the drink there. please, have a seat. >> why? >> have a seat. >> no. >> i'm chris hansen. >> yeah. >> i want to ask you some questions. please have a seat.

>> no. >> what are you doing up here? >> chilling. >> chilling? >> yeah. >> and who were you here to meet? >> her. have a good time. >> and how old is she? >> i don't know. she never told me. >> she never told you? >> she never told me. >> but as i refresh his memory with his own online chat, cisneros decides our interview is over. >> i want to point something out to you. >> i'm going to go. >> i'm chris hansen with "dateline nbc" and we are doing a story on adults who meet kids on the internet. >> get on the ground. now. get on the ground. >> i didn't do anything. >> the long beach police take cisneros to their processing center. >> it was just her. that's it. it wasn't -- you don't think about the age. you just think about doing it. >> sergeant lee debraybander of the long beach police. >> he knows what he did was wrong but he has this overriding problem in his mind and he needed to fill that need. >> later cisneros pleaded no contest to an attempted lewd act upon a child.

>> i think that was our walker. definitely, that was our walker. there he is. >> as in our previous investigations, some of the men who arrive aren't coming to meet girls. >> clear. >> and we've prepared for that. this decoy is a 21-year-old actor pretending to be a 13-year-old boy. >> hey, come on in. >> how are you doing? >> tommy. nice to meet you. >> nice to meet you. >> what's going on? >> not much. what's going on with you? >> nothing much. listen, i made up some drinks. so why don't you pour me some? >> meet 49-year-old rob culbertson, a computer web designer with the screen name webdev2. he's been chatting online with someone who says he's 13. culbertson lies about his age and says he's 40. and just like that earlier man, culbertson tries to get the boy out of his house. >> you want to come over? >> maybe. if you're cool. >> i'm laid back, no pressure. >> but when the decoy, instead,

suggests culbertson come over to the undercover house, the man makes it clear what's on his mind. >> let's meet. >> and? >> mess around. >> what's that mean? >> have sex. >> whatever he has in mind, we're about to find out he lives close by, and he rode his bike to our undercover house. >> so what you up to? >> oh, nothing. i was thinking of actually getting in the hot tub. do you think you might want to join me? >> that sounds cool. >> yeah? i'm a little nervous. so do you want to go first? take your clothes off? and we'll get in? >> i'm kind of nervous myself, too. >> yeah? >> culbertson seems to have second thoughts. >> actually, i think i should probably be going. >> why? >> because i'm not comfortable with this. >> why not? >> because of your age. >> how was the walk over? >> good. >> good. have a seat. what's your plan tonight? >> just out cruising around. >> just out cruising around.

how old are you? >> 35, 40. >> 35, 40? you don't know the exact age? >> i'm 40. >> we already know that's a lie. >> and how old is the boy you wanted to meet tonight? >> 18. >> how old did he say he was on the chat? >> 18. >> 18? >> yes. >> and can i give you the chat. i want you to tell me where it says that he's 18. >> i just went by what his profile said. >> his profile said he was 13. >> his profile said he was 18. >> no. he tells you right here he's 13. >> i apologize for all of this. >> "okay. i'm 13. damn, you are cute." he says, "but let's go a little slower, dude." >> like the other man, once i show him a copy of his online chat, culbertson decides it's time to go. >> so i'm going to be on my way. i'm sorry for all of this. >> before you go, there is one thing you need to know, and that is i'm chris hansen with "dateline nbc," and we're doing a story on adults who meet kids on the internet for sex. >> drop your bike. >> drop your bike. get on your knees. get on your knees. there you go. >> hands behind your head. >> hands behind your head.

>> lock your fingers. >> what's up? >> culbertson pleaded no contest to one charge of an attempted lewd act on a child. >> go to position two and call out. >> back at the house, our female decoy is about to say hello to 27-year-old justin smith, a video postproduction editor who does freelance work for nickelodeon, the cable network geared towards kids. using the screen name residentsmith, he chats online to a decoy who tells smith she is a 13-year-old girl. after the decoy sends a picture, smith writes, "it's definitely bad i think you're this cute, laugh out loud." the girl asks, "how come?" he writes back, "because i'm 27." he sends her several naked pictures of himself. but the next day smith seems to express regrets. "it can be dangerous," he

writes. the girl asks, "how come?" smith replies, "because it's illegal." over the course of 10 days, smith sends her links to 40 pornographic videos showing everything from oral sex to sex among multiple partners. he tells her when he comes over he wants to perform oral sex on her. and now here he is walking into the house. >> hey, come on in. how are you doing? >> good. how are you? >> awesome. >> good. >> i made us some drinks. >> awesome. >> and we have a hot tub. >> awesome. >> i really liked your videos, by the way. >> did you really? >> so how have you been? >> i've been good. it took me like 21 minutes to get down here because there was so much traffic. >> are you serious? where do you live? >> north hollywood. >> oh, that's not bad. >> we have a lot to talk about, you and i. why don't you have a seat right there, please. >> okay. >> no, i need you to -- >> i have to go, i'm sorry. >> you're going to want to talk to me. trust me on this. >> now, you work at nickelodeon, huh?

>> no. >> you don't? what's your name? >> police. get on the ground. >> get on the ground. get on your knees! >> put your hands behind your head. back of your head. >> i'm so sorry. >> on your need. both knees. >> i'm so sorry. i wasn't going to do anything. i swear to god. >> smith is taken to the processing center, where a police investigator interviews him. >> i will be lucky if i have any sort of resemblance to my job, my friends and my family, to the girlfriend i had. the daughter we have together. >> he knew coming in that what he was doing was wrong. that's why when he realized that he was caught and the ramifications on his life and everyone around him. that in my mind is why he became so emotional. >> smith later pleaded no contest to two counts. an attempted lewd act upon a child and attempting to send harmful matter. nickelodeon told us he fired smith and that he had no contact with children when he worked there. >> cell phones off. i need the mix in here of the decoy. >> with all this technology, a house bristling with hidden cameras, microphones everywhere, and 20 people crammed inside, some glitches are bound to happen. as it did when one of our

visitors arrived in his truck. >> hello? >> he's in the truck across the street. can you see it? walk down a little farther. there he is. all right. hold on where you are. >> 24-year-old case mahjoob, nicknamed matt, thought he was coming to see a 13-year-old girl. the decoy invites him inside. >> are you coming? how was the drive? >> mahjoob suddenly hears a walkie-talkie in the background. >> what? >> what's that? >> what's what? >> that sound? >> what sound? >> it was the decoy's walkie-talkie. instructions to her from inside the house were mistakenly broadcast in the driveway. mahjoob gets spooked, but he circles around and comes in anyway. >> come in. why did you go away? >> because i thought you had something to do with police. >> i'm not that retarded.

>> only mahjoob, screen name long beach dude 19, thought he was chatting with a 13-year-old girl. he tells her he'll perform oral sex on her. "i will show you heaven," he writes. "i love it. i can do that all day." mahjoob asks if she's performed oral sex, asks if she's good at it, and other specifics we can't tell you about here. and remember, he's chatting with someone who said she was 13. >> what have you been up to? >> not much. >> do you want to have a seat or something? >> give me a tour. >> give you a tour? >> yeah. >> let's see. well, this is the hot tub. >> cool. >> we can hang out here. >> really laid back here. >> hey, matt, how are you? now, matt, i need to talk to you for a minute. matt, why don't you have a seat right over there? >> but talking is not what he has in mind. >> get on the ground. put your hands up. hands up. both your hands up. >> put your hands up now.

>> follow the directions. >> he doesn't respond fast enough. the result is a taser shot. >> no! >> get on the ground. >> no! >> get him, cuff him. >> why was it necessary to use the taser on this guy? >> he's already demonstrated that he's not going to listen to the orders of the police officers. a lot of these guys, they are confronted with the reality that they are about to be exposed for what they did, and a lot of them may try violence to get away. the taser was used to prevent any injury to him and also to any police officers. >> at the processing center police find condoms in his car. he's pleaded guilty to an attempted lewd act on a child. coming up next, a man who has been our house guest once before. >> do you remember? we talked once before.

get on the ground! >> our undercover house in long beach is busy. 38 men are arrested over three days. but eight months earlier during our previous investigation in riverside, california this man, 26-year-old michael seibert, walked into our house. >> do you have a bathroom? >> back then, seibert had a

sexually explicit online chat with someone who told him she was 13, and he sent a picture of his genitals. >> hey, sir, why don't you come over here for a minute, please. >> seibert certainly had some explaining to do. >> why did you spend pictures of yourself like this to her? >> oops. >> oops? >> i will never do it again. i promise. >> you say a lot of sexually charged things to her for a 13-year-old girl. >> i know what i did wrong. okay? >> okay. >> it will never happen again. >> go ahead, you can leave. >> sorry about that. >> seibert told the riverside police he gets treatment for seizures and that the scar on his head was caused by a fall when he was an infant. >> do you work? >> yes. >> later he pleaded guilty to a charge of attempted lewd acts with a child and attempting to send harmful matter to a child with attempt to seduce. he was convicted and sentenced to 18 months in state prison. so fast-forward eight months

from our house in riverside to our long beach investigation. he's still online, still using the same screen name, and amazingly, still chatting with someone who tells him she's 13. just like his chat eight months before, he asks "have you ever had sex yet" and "i need sex." he also talks about group sex but is also suspicious and asks, "are you a cop?" to which she replies, "no, i'm not a cop." then apparently referring to his meeting with "dateline" eight months earlier he writes, "i got caught before." incredibly he tells the decoy he has to delay the long beach liaison for a day because he has to go to court, a court date to face charges arising from our riverside investigation. but the very next day -- >> hey, come here. >> -- here he is. >> we're not messing around with this guy. you do not let him get within six feet of you, eight feet of you. >> who is all here? >> just me. >> oh.

>> i promise. my parents are gone. >> you know, you look familiar to me. >> oops. >> that's right. oops, he's done it again. >> michael, right? >> oops, sorry. >> do you remember who i am? >> can i just go? >> what are you doing here, michael? >> i'm sorry. >> you were just in court on friday, right? >> mm-hmm. >> and what happened in court on friday? >> he said more time. >> more time before the next court date? >> yeah. i'm sorry what i did. >> okay. but you've got to the explain to me why or how you thought it was okay after having a court date stemming from our last visit and then within 24 hours you show up at this house to meet another young girl. what are you thinking about? now, you know -- >> i know. >> you know what you said online, right? >> yeah. >> how old is this girl? >> i don't know. >> 13. she told you she was 13. >> yeah.

i told her to go away. she keeps im'ing me back. >> you ask if she has got naked pictures of herself. you ask if she performs oral sex and what color her underwear is. now, michael, you know this is not right to do this, right? >> i know. >> we had this very same conversation in riverside, california. >> yeah. >> do you remember that? >> yeah. >> and right then you told me that you knew this was wrong and that you would never, ever do it again. that turned out to be a lie, didn't it, michael? >> i promise this time if you rip it up, i'll never come back. >> but if he appears to be a sad case, you should know that according to perverted-justice seibert has had sexual chats with at least three other decoys who said they were underage girls. and you should also know that there is another side to seibert's story. he served a year in jail for a dangerous assault.

>> what was the deadly weapon you used in the assault? >> a bat. >> and who did you go after with a bat? some guy? is there anything else you want to tell me, michael? >> you did wrong. >> can i go? >> michael, you can go, but i'm going to remind you that i'm chris hansen with "dateline nbc" and we're doing another story on adults who try to meet kids on the internet for sex. >> i know i did wrong. >> you can go. you can go right now and walk right out that door. >> any cops out there? s >> that's not up to me, michael. >> yeah, it is. >> i'm not the police. so why don't you go ahead, michael. it's time to go. >> seibert clearly doesn't want to leave. having been through this before, he knows the police are waiting outside. >> [ bleep ]. i need a bathroom.

>> michael, you're going to have to go outside. >> i know, i am. >> now, walk out. walk out. get on your knees. >> like the others, seibert is charged with an attempted lewd act upon a child. he pleaded no contest. his lawyer says seibert has severe mental issues. is that a defense in any way in this case? >> in my mind, no, it's not a defense. he knows what he did was wrong. he knew enough that when you confronted him his first words were "oops." he knew enough to promise you that he wasn't going to do this again. >> do you live with your mom? >> yep. she's going to kill me. >> he admitted to me during our interview that he had been previously convicted of assault. >> yes. >> what does that say about the danger he could present to a young teen home alone? >> my biggest fear is that he would show up, the young teen would decide not to go through with what they had been talking about in their internet chat, he would become frustrated with that, and his violent nature would come out. >> seibert was convicted on the long beach charge.
